Diagnostic tool - Guzzidiag for RSV4

Just letting anyone interested in diagnostic tool for RSV4 to know about very inexpensive alternative to Technoresearch Centurion. You can get the latest software here: http://www.von-der-salierburg.de/download/GuzziDiag/ There is also instructions of getting the adapter and how to install etc. You can find the adapter(s) in ebay for about 20 euros total.

I have been testing it last few months on my RSV4, identifying channels etc. and letting Beard know what needs changing and so on. Beard has done good job on this! And there is more to come (throttle calibration etc.), stay tuned

So to get it working with RSV4 you should choose California 1400 as the motorcycle (it has the same MM 7SM ECU as RSV4). At the moment you can read and clear faults, do some functional testing (for example turn on fuel pump, throttle/handle learning, read sensor data. There are still few channels I'm working on.

If you get it running and have some comments, or improvement ideas, please let me know! I can forward wishes to the developer. If you like the software, there is donate button to send thanks to the developer, but otherwise the software is free.

Just to clarify that I'm not selling anything here! I have just been testing Guzzidiag for Beard, since he don't a have bike with 7SM ecu. I just would like to people to know about this free (ok, 20 euros is not free..) tool that can save you from an expensive trip to dealer!

****************EDIT*******************
Due to long thread already, added a FAQ for the newcomers to get started.

1. What interface is needed?

a. You need two adapters

i. USB to KKL (OBD2). Make sure it has FTDI 232RL chip
ii. OBD2 16-pin to 3-pin, also called as FIAT adapter

2. Where to get them?

a. Links to known good cables are at the bottom of the Guzzidiag page
b. You can get them also from ebay, see #1 for specs. But don’t come asking here is this or this good cable. There are hundreds of sellers and different versions etc. no one has tried and tested them all. Even same seller can have different batches with different specs.
c. One good source for the cables is this: http://lonelec.co.uk/index.php?route...&product_id=51

4. Now I’m confused, there are Guzzidiag, IAWDiag, IAWReader, etc… in this web page. What do they all do?

a. Guzzidiag and IAWDiag were separated to have Guzzidiag dedicated to Moto Guzzis and IAWDiag to other bikes using MM IAW ECUs
b. IAW Reader, IAW Writer are for programming ECUs.

5. What I can do with IAWDiag?

a. Read and clear fault codes (if you have SERVICE text on the dash, it means there is some fault code stored in your ECU)
b. Read active sensor data
c. Check map version
d. Do throttle/handle learning
e. Do some active tests, activate injectors etc. to help with diagnostic
f. Install new ECU (race ECU for example) to your bike IF in the new ECU mapping is correct, APRC/ABS/QS configuration is correct to your bike, and CLF does not need encoding (in some very rare cases in APRC bikes the CLF ECU needs encoding to start working with a new ECU). See #6 for the IAWDiag limitations.

The 3-pin adapter is correct for sure, and the USB-KKL adapter looks right, but there are different versions of the FTDI chip in these adapters and it does not say which one it has (or does it even have FTDI chip..). Anyway if it has FTDI chip it is matter of getting the correct driver to go with it, so you should get it working regardless. I would install the FTDI driver that is listed at the end of guzzidiag web page before connecting the adapter to your PC, just to be sure and avoid having to uninstall the drivers Windows installs automatically.

RL is a newer chip, BL is not good enough I think.
Most time supporting Guzzidiag is gone to people buying wrong adapters. The ones sold through Amazon give most problems because you don't know what you get there. For them any KKL is the same.

Beard is working on the MacOS and Linux versions before release, but I'm expecting it to be ready in next few days.

No plans for the TB sync yet since it can be done the "old" way with vacuum gauges and it is more of a feature of the PADS/Navigator telling how much to turn which air bleed screw than ECU test mode which is commanded from diagnostic system. That being said I'm doing TB sync for my bike soon and I'll try to figure out how to interpret the sensor data to see when the TBs are in sync. I'll let you know how it turns out.

Thanks. The other reason, I guess, why TB sync function might be helpful is AFAIK the adjustment screws are accessible without removing an air box. In order to do sync the "old" way you'll need to remove/install air box at least twice.
